A couple of trans wiring questions

[silverado_lover]

Alright guys so the first question, on my 95 harness by the main trans connector there's a 3 pin wire that I can't find where in the world it plugs in, I've spent about an hour trying to feel for a plug but had no luck. Whenever I turn the key I can see what gear I'm in but once I start the engine the gear indicator goes away.
I'll post a pic of what I'm talking about when I get on my laptop.

Secondly where do I find the wire for my park/neutral ground? The wire from the standalone is orange

I'm starting to think it could be my old o2 sensor connector

Alright so that extra connector is for the old o2 sensor.

Still don't know where the neutral safety ground is, Haynes manual is right in front of me.

The only thing I need to suggest to you is in that pic get rid of those blue scotch locks or whatever you call them and solder and heatshrink those wires or I promise those things will give you problems down the road when the wires turn green.

everything is getting soldered once I get it running right
